Patient choice and treatment alternatives for arthritis

Two new studies investigated patients' decisions regarding therapy for rheumatoid arthritis (RA) and glucosamine use for osteoarthritis, finding that most RA patients prefer to maintain their current treatment as long as their condition doesn't worsen. The studies also highlighted discrepancies in clinical trial results for glucosamine...

Pairing nanoparticles with proteins

Researchers demonstrate ability to attach gold nanoparticles to proteins, forming protein-gold arrays for deciphering protein structures, identifying functional parts, and targeted drug delivery. Applications include catalysts for biomass energy conversion and precision vehicles for tumor targeting.

UCLA study first to show autistic brains can be trained to recognize visual and vocal cues

Autistic individuals often struggle with interpreting subtle social cues like facial expressions and tone of voice. A UCLA study found that explicit instructions can train their brains to respond appropriately. Researchers trained ASD children to pay attention to these cues, resulting in increased activity in the brain's 'social' network.

Outdoor alcohol ads boost kids' urge to drink

A University of Florida and University of Minnesota study shows that adolescents attending schools in neighborhoods with high alcohol ad presence tend to want to drink more. The study found that exposure to outdoor ads boosts kids' urge to drink, even among those who weren't drinking previously.

Researchers find gene that spurs development of the epididymis

A team of researchers at the University of Illinois has discovered a key gene involved in the development of the epididymis, a critical structure for sperm fertility. The gene, inhibin beta A, plays a vital role in stimulating cell growth and differentiation, leading to the formation of the epididymal tube.

'Cars' imaging reveals clues to myelin damage

Purdue researchers used CARS imaging to study how the myelin sheath is degraded by lysophosphatidylcholine. The findings suggest that calcium ions activate enzymes that break down proteins and molecules in the myelin, leading to its degradation. This research may lead to new treatments for multiple sclerosis.

Antibodies protect mice from developing respiratory tularemia

Researchers have found that treating mice with tularemia-specific antibodies can protect them against the bacteria, enhancing immune responses and acting as a surrogate vaccine. This approach could be particularly useful in cases of bioterrorism, providing rapid and specific protection to individuals with weakened immune systems.

Green Junta

Cardiff University's Peter Wells warns that a 'Green Junta' could bring about an authoritarian agenda in the name of sustainability. He argues that consensus among multiple stakeholders is increasingly inadequate to create sustainable societies, and a strong government may be necessary to implement drastic changes.

NOAA scientists to search tropical skies

Scientists from NOAA's Earth System Research Lab will conduct a field study in Costa Rica to observe the troposphere during the rainy season. They aim to understand key processes related to climate change, the stratospheric ozone layer, and global chemistry.

Neutron stars join the black hole jet set

The discovery reveals how efficient neutron stars can be as cosmic power factories and shows they rival black holes in generating powerful jets. The X-ray jet is found to be almost as efficient as one from a black hole, with a surprising high percentage of energy converted into powering the jet.

A genetic factor predicts prognosis in brain tumor patients

A genetic factor has been identified that predicts prognosis in brain tumor patients. The Notch2 gene is a key regulator of developmental processes and its loss positively predicts survival in subgroups of brain tumor cases. This finding offers new targets for molecular intervention to develop drugs against this severe human disease.

Female iguanas pay high costs to choose a mate

In a study on female Galápagos marine iguanas, researchers found that females devote substantial energy to picking among suitors, with visiting attractive males carrying the highest costs. This includes weight loss and reduced egg production, as well as decreased chances for survival during food-scarce seasons.

Drugs used to fight cancer-related bone problems boost odds of jaw- or face-bone disease

A large-scale comparative study has found that treatment with intravenous bisphosphonates increases the risk of jaw or facial bone disease or infection. After six years, about 5.5% of bisphosphonate users had undergone facial or jaw bone surgery or been diagnosed with inflammation of the jaw bone, compared to 0.3% of non-users.

Why do power couples migrate to metropolitan areas? Actually, they don't

A new study challenges prior research on power couple migration patterns. Researchers found that college-educated singles are more likely to move to big cities where they meet and marry other educated individuals. This finding has implications for city planners seeking to attract a well-educated workforce. Power couples with only one c...
